Title: Improvements in the manufacture of moulded articles
IPC: D21C11/00
Filed: 1946-09-30
Abstract: Plastic compositions are prepared by mixing sulphite cellulose waste lye, which may be practically freed from its sugar content and may contain about 8 - 10 per cent dissolved solids, with animal albuminoid substances in the presence of a finely divided carrier causing the separating ligno-gluten to be directly precipitated on the carrier, the precipitation being preferably effected by the addition of a precipitating substance such as a dilute mineral acid, the product then being moulded and hot pressed at a pressure of 10,000 to 400,000 kgs. per m2.  The carrier may be wood waste paper or mixtures thereof, which may be obtained in the manufacture of cellulose, stone powder, cork-powder, sawdust, asbestos, sand or cement, or a mixture of two or more of these, or there may be used a cellulose-containing fibrous material such as wood pulp, cellulose, waste paper or mixtures thereof, which may be used in conjunction with peeling chips.  Preferred albuminoid substances are the dilute gelatin solution obtained as a waste product in the manufacture of glue, and the skim milk obtained when manufacturing cheese.  The products may be rendered less inflammable by the addition of sodium or potassium silicate; formaldehyde, or a substance which generates formaldehyde on heating, may be added to the composition before moulding.  The carriers may be coloured or coated with wax or cellulose lacquers, and pressed slabs manufactured from peeling chips may be provided on both sides with veneers.  Specifications 500,229 and 586,764 are referred to.

Patent GB-292525-A (GB)
Abstract: 292,525. Burroughs Adding Machine Co., (Assignees of Pasinski, W. J.). July 19, 1926, [Convention date]. Divided on 274,411. Transfer-mechanism. -A bail for temporarily holding any tripped transfer sectors and for restoring them after they have been fully actuated to effect transfer, is directly timed in its movements by means controlled by the displacement of the counter into and out of engagement with the actuators. The invention is illustrated as embodied in the machine described in Specification 274,411. The spring-impelled transfer sectors 120 are normally held against counterclockwise movement by detents 123 forming part of yokes the other arms 126 of which extend rearwardly to be engaged by pins 128 on trip levers 130. At transfer therefore the wide tooth on the lower wheel rocks the trip lever to remove the detent from the sector which thereupon shifts counterclockwise slightly until its tail rests on a bail 133. In this position the sector underlies the nose of the the detent to prevent resetting of the parts. At the end of the return stroke of the machine and after the counter has been disengaged from the actuators, the bail is lowered to allow the sector to turn fully counterclockwise to effect transfer. The bail is secured upon a shaft 136 and one of its side arms is extended at 137 to co-operate with a pair of spring-connected latches 138, 139 suspended at 140 on the counter-supporting frame. The bail is operated by a spring 157, Fig. 7, connected at one end to an arm 155 loose on shaft 136 and at the other end to an arm fixed to the shaft. The arm 155 is rocked to tension the spring 157 during the forward stroke, by a link 154 attached to a pivoted cam arm 152 rocked clockwise against the action of a spring 159 during this stroke by a pin 151 on an arm fixed to the oscillated shaft 400. At the beginning of the stroke therefore the spring 157 tends to raise the bail but this is prevented by latch 139. When, however, the counter has moved away from the transfer sectors the latch 139 has moved counterclockwise far enough to free the projection 137 and allow the bail to restore any released sectors after which the bail is held up by the hooked end of latch 138. When towards the end of the return stroke the counter is moved again into mesh with the sectors, latch 138 releases the bail to allow it to be restored to normal position by the action of spring 159 and arm 155. To prevent rebound of the actuator racks 610 when restored and thereby an undesired transfer a comb 162 carried by the counter frame has its tines bent upwards to serve as stops for pins 163 on the racks. The counter pinions are aligned and held when shifting from the transfer sectors to the actuators and vice versa by means of a bail 142 one of the supporting arms of which is shaped at 147 to coact with a stationary rod 148 so that the bail engages with and disengages from the pinions as they pass from one set of gears to the other.

Title: An improved process for the separation of olefins from hydrocarbon mixtures
IPC: C07C7/11
Filed: 1938-10-14
Abstract: 523,894. Olefine separation. STANDARD OIL DEVELOPMENT CO. Oct. 14, 1938, No. 29852. Convention date, March 29. [Class 2 (iii)] Olefines having two to five carbon atoms are separated from mixtures with saturated hydrocarbons by first absorbing them in sulphuric acid of a concentration stronger than that normally used for converting the olefines into alcohols, and then heating them without dilution with water in the form of a thin film to a temperature higher than the boiling point of the corresponding alcohols, the liberated olefine being rapidly removed in order to avoid polymerization. Preferably the acid-olefine reaction mixture is supplied to the top of a column packed with a suitable filling material such as Raschig rings and heated with steam to a temperature at least 10‹C. higher than the boil ing point of the corresponding alcohol ; the gas evolved is rapidly withdrawn, e.g. under reduced pressure, from the top of the column and the acid removed at the bottom. Taking propylene as an example, a sulphuric acid of 60-85 per cent. concentration is used for the absorption and a temperature of 170-200‹C. for the subsequent regeneration. The residual acid is recycled to the absorption stage, preferably after adding an amount of water sufficient to compensate for the water removed as alcohol or ether, or is used for the absorption of other olefines. To assist in the absorption, a proportion of the olefine may be allowed to remain in the acid; also, any alcohols or ethers produced may be returned to the acid before or after the absorption stage. Examples are given relating to the recovery of isobutylene. The Specification as open to inspection under Sect. 91 also refers to the treatment of hexylenes and heptylenes, and to the use of phosphoric acid, or mixtures of phosphoric and sulphonic acids, or benzenesulphonic acid as absorption agents. This subject-matter does not appear in the Specification as accepted.
